OIL BURNER.

Application filed September 20, 1927. Serial No. 220,735.

This invention relates to oil burners of that class wherein oil is mixed with steam and air and projected in the form of a jet into the furnace.

The general object of the present invention is to so form the burner as to secure a better and more perfect mixing of the oil, steam and air, and to provide means whereby the amount of air mixed with the oil may be controlled.

A further object is to provide an air head, as it may be termed, forming part of the forward end of the burner which secures its air from the fire box so that hot air is mixed with the atomized oil and steam so as to secure a perfect combustible mixture.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawing, wherein Figure 1 is a longitudinal sectional View through an oil burner constructed in acoordance with my invention;

Figure 2 is a front elevation of the burner;

Figure 3 is a section on the line 33 of Fi re 1;

fi dferring to the drawing, 10 designates an oil pipe, which is preferably of uniform diameter from end to end and which preferably has an internal diameter of not less than Surrounding this oil pipe 10 is a steam pipe or chamber 11 which toward its forward end is contracted, as at 12. The rear end of this annular steam chamber or pipe which surrounds the oil pipe is connected by a branch 13 to a source of steam under pressure. The forward end of the steam pipe 11 is partially closed by a wall 14 having a circular series of apertures 15 therein through which the steam is discharged in the form of a plurality of jets.

Surrounding the forward end of the steam pipe is an air mixing sleeve, designated 16, which is slidably mounted upon the oil pipe 11 and is held in any adjusted position by means of a screw 17. This sleeve 16 is formed with an annular air inlet channel 18, which channel extends into the space between the steam pipe 12 and the air sleeve. This air sleeve is disposed Within the fire pot of a furnace, to the extent at least that the channel 18 receives hot air from said fire pot and this hot air passes through the openings 19 in the channel into the interior of the sleeve where it is mixed with the steam and oil discharged out of the pipes 10 and 11. By sliding the sleeve 16 backward or forward, the hot air may be regulated to suit the fire needed.

In the operation of this burner, the oil discharging from the extremity of the pipe 10 drops downward over the small perforations 15 in the steam chamber or pipe and the jets of steam projected against the oil cause the oil to be thrown upward where it will be struck by jets of steam projected from the upper holes 15. Thus the oil is subected to the action of the steam projected from all of the holes 15 which causes a thorough intermingling of the oil with the steam and atomizes the oil. At the same time the oil and steam are thoroughly intermingled with the air in the sleeve 16 and the air, steam and oil are projected into the furnace for combustion. It will be seen that when the jet so formed is projected out of the mixing sleeve, it is in the form of vaporwhich spreads to a considerable size. The oil is thoroughly broken up before firing and, of course, the more the oil is broken up and atomized, the better will be the combustion. A further advantage of this burner lies in the fact that the burner can never clog and it can be cleaned very much as a shot gun barrel is cleaned with a cleaning rod without taking the burner down or tearing it apart. The burner, therefore, may be readily cleaned and is in condition to use at all times. This is due to the fact that the oil pipe is relatively large and perfectly uniform in diameter and has a straight line through the steam chamber or pipe.

I claim In a furnace having a fire box, an oil burner comprising a centrally disposed oil pipe, a concentrically disposed steam pipe terminating at one end with the discharge. end of the oil pipe and being connected thereto at this end by an apertured wall, the apertures being arranged concentrically to the opening in the steam pipe, an air sleeve surrounding the forward end of the steam pipe and being longitudinally adj ustable thereon and spaced from the steam pipe and extending beyond the same, the rear portion of the sleeve having an inwardly extending hollow rib concentric to the steam pipe and disposed closely adjacent thereto,

this rib being formed with a plurality of perforations, the air inlet openings of this air sleeve being disposed Within the fire box.

In testimony whereof I hereunto afiix my signature.
